To all whom it may concern:

Be it known that I, FLORIAN WV. WEBER, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Antiskid Devices for Vehicle 'Wlieels, of which the following is a specification.-

My invention relates to improvements in antiskid devices for vehicle wheels, and has for its object the production of a device of this character which will be of extremely simple and economical construction, one which may be readily and easily applied, and which will be highly eflioient in use. i

A further object is the production of an anti-skid device, as mentioned, in which the parts will be so connected as to permit of ready replacing or renewal of parts when the same become worn or disabled.

Other objects will appear hereinafter.

\Vith these objects in view, the invention consists in the combinations and arrangements of parts hereinafter described and claimed. 7

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a side elevation of a fragment of a vehicle wheel equipped with an antiskid device embodying the invention,

, Fig. 2 is an enlarged'detail section taken through one of th connections between the cross and side members of the device,

Fig. 3 is an enlarged section taken on line 33 of Fig.1, j 1

Fig. 4 is a detail side elevation of the por tion'of the device at the-point of connection of the ends of one of the side members, portions of the construction being broken away in order to expose underlying parts, and

Figs. 5, 6 and 7, are sectionstaken on lines 5-5, 6-6 and 77 respectively, of Fig. 4-.

The preferred form of construction, as illustrated in the drawings, comprises-a plurality of spaced cross members lOwhich are adapted to extend transversely across the treadof the wheel 11 in conjunction with which the device is employed. The cross members 10 are arranged in pairs, each pair being formed of a single piece of material which is bent uponitself into substantially elongated looped or oval form, as clearly shown in Fig. 1. The ends of the liiBiI1- her from which each pair of cross members 10 is formed are securely connected together by means of a sheet metal connecting device 12 one end of which is looped or Wrapped around the contiguously positioned ends of said member and pressed into secure engagenient therewith. To securely hold said ends in engagement with the embracing portion of said connecting member, the latter is preferably provided with a'prong 13 which pierces the member 10, as seen in Fig. 2. At the opposite side of the wheel, or at the biglit portion of the member from which each pair of cross members 10 are formed, is provided a similar connecting member 12 which similarly embraces the same. Each member 12 is formed with a tongue or hook 14 and a re taming tongue 15 stamped from said member which is adapted to cooperate with the tongue 14, that is to engage against the outer sidethereoi in order to hold the same in op erative position, as clearly shown in Figs. 2 and 4.

Provided at the opposite sides of the wheel, extending around the same, are annular side members 16 to which the connect ing members 12 are fastened. The connection between the members 12 and the side members 16 comprises a plurality of sheet metal connecting members 17 which are spaced along each of said side members, one end of eachof said connecting members 17 being looped or wrapped around the member 16, as clearly shown in Fig. 2. Each of said members 17 is formed with a lug or lip 18 in which is formed a slot 19 adapted for engagement with the reduced outer end of the tongue 14 of the corresponding connecting member 12, as seen in the several views. In order to securely lock the connecting members 17 to the side members 16, the former are provided with prongs 20 Which pierce the members 16, as seen in Fig. 2. The lips or lugs 18 are ofl set as at 21, in order to accommodate the inner side of the corresponding tongue 14 so as to present a surface without obstructions or protrusions for contact with the side of the tire and thus reduce wear upon the tire to a minimum. The ofi'-set 21 in each member 17 also affords a shoulder which engages against the end of said member which is wrapped around the side members 16, serving to hold said end in embracing position, as seen in Fig. 2. Also, the shoulder formed by said ofi?set is adapted for engagement with shoulders 21' on the tongue 14, as shown in Fig. 4, in order to other end bar 35 of the buckle.

serve as a means of preventing relative lateral tilting of the members 12 and.17. The prevention of such tilting of said parts insures against the reduced ends of the tongues 1 1 being bent and possibly torn off under heavy lateral pressure, such as the same would be subjected to where the device is used in connection with a heavy truck. In assembling the parts, that is in engaging the connecting n'iembers 12 with the connecting members 17, the retaining tongues 15 are bent outwardly and the outer ends of hooks 14 are bent to a position to permit of the same being inserted into engagement with slots 19. After said tongues 1% have been engaged with said slots, the same are bent into closed or operative position and theretaining tongues 15 bent into engagement therewith, as seen in Fig. 2, thereby securely locking the connecting members together. The connection is such, however, that in case of wear or disabling of the cross members 10, said connecting members may be readily disengaged in order to permit of the insertion of new parts.

The ends of each of the side members '16 are adjustably connected together bymeans of a flexible strap 22 and a cooperating buckle 23. In order to accommodate these parts, the ends of each side member are provided with sheet metal end members .24 which are formed to embrace the ends of said side members, the same being rigidly secured thereto, as by'means of rivets 25, or other suitable means of fastening. One of the end members 2-1 is formed with a loop 26 which embraces a cross bar 27 of the buckle 23. To another cross bar 28 of said buckle is secured one end of the strap 22, said strap extending therefrom around a. roller 29 provided upon one side of a link or loop 30 carried by the end 31 of the'other member 24, said strap 22 then passing under the end bar 32 of the buckle andaround the toothed end of a pawl 33, pivotally mounted upon another bar 3 1 of the buckle, whence the end of the strap is passed around the The arrangement is such, as will be seen, that-the ends of each side member may be readily adjusted through manipulation of the strap 22 in order to properly adjust the crossmembers 10 t0 the tread .of the wheel. In order to lock the pawl 33 in operative position, that is in looking engagement with the strap, a laterally projecting keeper 36 is shiftably mounted at the under side of the pawl for engagement under one side of the buckle frame, as seen in Fig. 4. The keeper 36 is formed with .a button 37 positioned at the upper side of the pawl which maybe readily engaged by the thumb or finger in shifting said keeper. The pawl is slotted, as seen, to afford shifting for the keeper.

Each of the end members 24 is formed With an elongated lip 38 in which is provided a slot .39 adapted for engagement with thetongues 1 10f connecting members 12, the engagement of the tongues of said connecting members being precisely the same as the engagement thereof with the connecting'members 17, above described. The inner or rearward sides of-the lips or lugs38 are recessed, or cut away, in order to acco-mmodate the corresponding sides of tongues It so as to provide a smooth surface without obstructions for engagement against the side of the tire.

With the construction set .forth, it will be seen that an anti-skid device is provided which vmay be readily "and easily adjusted to position upon a wheel and asreadilyand as easily removed therefrom. In case of Wear of thecrossmembers 10, the samemay be readily and easily'detached and replaced with new-ones. Tlre cross members 10 and side members'lG are formed preferably of rope-or other fibrousiflexible material which is chemically treated, as by impregnating the same with parafiin, or other suitable agent, in order to :render the same waterproof and weatherproof. Also, in the connection of said cross members and side members with the various metallic devices engaging 'therewith, cement or other connecting agent may beemp-loyedto insure a rigid connection.

The/arrangement-of the cross members in pairs, with the ends of the members of each pair connected together, as shown and described, is of specialadvanta'ge in that, with this arrangement, the members of each pair of cross pieces cooperate with each other-to effectively preventskidding. 'With this arrangement, when the brakes of the automobile are applied, as the cross pieces are brought into engagement with the pavement, one of the members of each pair of cross pieces will engage with .the ground before the other. This being the case, thecross piece of each pair, contacting with the ground, will exert a pull rearwardly which will cause the-other cross piece to be drawn vinto secure clamping engagement with the tire. This :will :relieve the strain upon the side fastening devices, and also prevent rotation of :the wheel relative to the anti-skid device. .It will-thus be'seen that the two connected cross pieces cooperate with each other ii -securing more eifective engagement with the gronnd,-.and .in more effectively preventing slipping of the tires upon the pavement.

lVhile I have illustrated and described "the preferred form of construction for carrying my invention into efi'ect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise=deta11s of construction set forth, but

desire to avail myself of such variations and modifications as come within the scope of the appended claims.
